After eight years of hard work, the day has finally arrived. Today, September 14, the Haiku project has released its very first alpha release. With the goal of recreating one of the most beloved operating systems in history, the BeOS, they took on no small task, but it seems as if everything is finally starting to come together. Let's talk about the history of the BeOS, where Haiku comes from, and what the Alpha is like.

I just found the option to have Tracker work with only one window, which works best for me usually, but is there any quick way of opening a specific folder in a separate window?

Try Ctrl-Option (Windows key)-up arrow & down arrow. I use Tracker in "spatial" mode, so I can't say for certain - but in spatial mode those are the keyboard shortcut for "open parent/selected folder and close the current folder." So I'm guessing they do the reverse (what you want) in single-window mode.

And, talking about key combos, I'm a keyboard lover. I rarely ever use my mouse for anything other than navigating in web pages. But I'm in need for keyboard shortcuts to do stuff like window cycling (alt-tab) and acessing the applications menus.

Alt-Tab will work, but a bit differently than in Windows - you need to hold Alt-Tab down for a few seconds before the pop-up appears (although it will still switch between applications if you just tap Alt-Tab).

Accessing menus can be done with Ctrl-Esc. You may need to change the "shortcut key" setting - BeOS used Alt by default (so copy was Alt-C, past was Alt-V, etc), but I don't remember if that's the case with Haiku. The setting should be under the Haiku menu > Preferences > Menu.
